AME 655 – without safety function
AME 658 SU, AME 658 SD – with safety function (spring up/down)
AME 659 SD – with EN certified safety function (spring down)

Actuators are primarily designed to regulate valves in response to the demand of a controller in District Heating/cooling, Heating, Ventilating and Air conditioning systems.
Actuators AME 655, 658 and 659 can be controlled by electronic controllers with modulating or 3-point control output.
Please check power supply and power consumption prior to connection!
Actuators can be used in combination with:
– Valve types VFM, VFS (DN 65-100), VFG(S), VFU, VF (DN 100-150) and VL (DN 100)
– Self-acting flow controller AHQM (DN 125-150), AFQM 6 and AFQM PN 25

Features:

• Manual operation, either mechanical and/or
  electrical
• Position indication
• LED signalling
• Selectable speed
• Inverse function
• Automatic adaptation of stroke to valve’s end positions that reduces commissioning time (self stroking)
• Integrated external switch
• Characteristic optimization
• Stroke limitation
• Pulse or continuous output signal (4, 5)
• Voltage or current input signal Y
• Voltage or current output signal X
• External reset button
• Auto detection of Y signal
• 3-point or modulating control selection
• X and Y galvanic insulation
• Thermical and overload protection
• Precise regulation and fast response on 3-point signal (0,04s)
